What is the cause of malposition? How to correct it

4hw.com.cn: I believe that mothers know more or less how fetal position is. If there is an abnormal fetal position, most mothers will be confused. What are the causes of the abnormal fetal position and the correction methods? Let's follow Xiaobian to learn more about it~

What is placentation

Let's learn about placentation first. The so-called fetal position, generally speaking, is the position of the fetus in the womb. The position of the fetus in the womb before birth is very important. It is related to whether the pregnant woman has a smooth or difficult delivery.

Clinically, doctors will use some terms to describe the position of the fetus in the uterus: axial refers to the direction of the fetal axis relative to the maternal uterine axis, including long axis position, transverse position, and oblique position. However, the axial position cannot tell us which part of the fetus comes out first. For example, the long axial position may have the fetal head below or above (hip position), so other terms need to be used to further describe the detailed position.

Causes of malposition

The normal uterus is pear shaped, that is to say, the lower part of the cervix is smaller, while the upper part of the uterine top has a larger space, so the fetus will naturally head down according to the shape of the uterus at full term, and the feet participating in activities at the buttocks will form a 'head position' at the upper part of the uterus with a larger space. As for the occurrence of malposition, we must consider the shape of the uterus, the amount of amniotic fluid and the size of the fetus, so the incidence of malposition is not the same in different gestational weeks.

Abnormal fetal position generally refers to the abnormal position of the fetus in the uterus after 30 weeks of pregnancy vibration, and it is more common in pregnant women with loose abdominal wall and pregnant women. Because the abnormal fetal position will bring different difficulties and risks to delivery, it is of great significance to correct the fetal position in early stage for the prevention of dystocia.

If the fetal position is not correct, the doctor will discuss with the pregnant woman how to choose the best mode of production. If the fetal position is changed to head position after adjustment, the vaginal mode of production is the first choice. If the adjustment does not come back, the cesarean section may be a safer mode of delivery. The doctor will analyze the advantages and disadvantages and let the mother, family members and doctors make a choice together.

Correction method of fetal malposition

Generally, the abnormal position found before 7 months of pregnancy can only be observed more intensively. Because before 30 weeks of pregnancy, the fetus is relatively small compared with the uterus, and the mother has more amniotic fluid in the uterus, so the fetus has room for movement, and will correct the position of the fetus by itself, and most of them can naturally turn to the 'head position' after 30 weeks of pregnancy. However, generally speaking, if the fetus is not in the right position at 30-34 weeks of gestation, it needs to be corrected. The specific correction methods are as follows:

1. Correction of knee chest lying position

Pregnant women empty their bladder, loosen their belts, put them on a rigid bed, push up, put their knees on the bed, lift their hips high, keep their thighs perpendicular to the bed, and try to keep their chest close to the bed. One time in the morning and one time in the evening, each time for 15 minutes, one week in a row. Then go to the hospital for reexamination.

2. Doctors perform 'turning' for pregnant women

If the fetus does not turn around at 32-34 weeks of gestation, the doctor should consider carrying out the external transfer operation for the pregnant woman, so that the fetus can turn over and the pregnant woman can give birth smoothly. It should be noted that there is a certain risk of fetal transfer. During operation, umbilical cord entanglement or placental abruption may occur. Therefore, this method is not popular in areas with advanced science and technology and conditions for cesarean section.

3. Acupuncture treatment for malposition

In view of the malposition of fetus, there is a successful precedent of acupuncture treatment in China. It is suitable for pregnant women with hip, transverse and oblique position diagnosed by gynecological examination.

4. Self correction method

Can do knee chest recumbent exercise correction, morning and evening each time, each time do 10 minutes, continuous do 1 week, fetal position can be positive. The posture is: on the hard bed, the chest and knees are planted, the hips are raised, the thighs are vertical to the bed, the chest should be close to the bed surface as much as possible, but the trouser belt should be loosened before making.

Note: the sick woman should not sit for a long time and lie down for a long time, but should increase such gentle activities as walking, kneading the abdomen, turning the waist, etc.
